Rockfish are assessed on a biennial stock assessment schedule to coincide with the availability of new trawl survey data. For Gulf of Alaska rockfish in off-cycle (even) years, we present an executive summary to recommend harvest levels for the next two years. Please refer to last year’s full stock assessment report for further information regarding the stock assessment model (Shotwell et al., 2015, available online at http://www.afsc.noaa.gov/REFM/Docs/2015/GOArougheye.pdf). A full stock assessment document with updated assessment and projection model results will be presented in next year’s SAFE report.
